WASHING MACHINE.

Application filed October 16, 1923i Serial No. 668,881.

'[0 all whom t may concern:

Be it known that I, ALLAN FRASER Mc- NAUGHTON, a subject of the King of Great Britain, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful improvements in `Washing Machines, of which the following is a specification.

This invention relates to a domestic clothes washing machine of that class wherein the clothes are alternately squeezed against and released from'the opposite sides of a spari-ed cage, within a water container, by the oscillation of a similarly sparred cage mounted between the sides of the containing cage.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Fig. 1 is a side elevation of the washing mechanism the front wall of the tank being removed and parts of the inner and outer clothes cages being in section.

Fig. 2 is a plan of the same, half of the oscillating cage being removed.

ln these drawings 2 represents the water holding tank, within which the washing is effected and which is supported in any suit,`

able manner at a convenient height from `the ground for the user. On the bottom of this tank members 3 are secured in thefmiddle of each side, which members are notched from the upper side as at et to receive pins 6 projecting from the ends of a centre board 7, which extends across the bottom of the tank between the members 3;

rEhe members 3 are also notched as at 5 t receive pins 8 projecting from the lower ends of the side members 9 of a cage frame composed of these side members with bars or rails 10 of wood extending between them, the ends of the rails being tenoned into elongated slots in the members 9.

The side members 9 are curved upward and outward from their pin-connections 8, and the lower edges of the rails project beyond the upper edges of the same, so as to offer a shouldered surface during upward movement of the clothes past them, as will be better understood later when the operation of the machine is described. A space is left between the rails sufficient to permit free passage of the water but preventing passage of the clothes.

The upper end of each side member'9 has provision at l1 forvsecuring it yto the adjacents'ide of the container, which securing means 1s removable to allow theupper edge of the cage frame on each side to be opened outward, see dot and dash lines in Fig. 1, t facilitate entrance of the clothes to be cured immediatelyv Within the sides of the` tank, between which frames a series of wooden rails 15 extend in a manner similar to the rails 9 of the stationary cage, that is, the frames are provided with slot vholes to receive tenons formed onl the end of the rails. The outer faces of these railshave rounded edges, the upper one of which' projects beyond the lower one of the same that the shoulders formed by the projecting edges of the rails 15 may oppose those of the rails of the stationary cage.

The shaft 12 with the inner cage 14, 15 secured on it is oscillated by a handle lever 16 secured on one or both ends of it, that the cage 14, may be manually oscillated within the limits of the fixed cage 9, 10.

To prevent the clothes from working out from between the cages during oscillation, members 17 are removably secured in the upper part of each frame 14 on each side, which members carry a rail 18 between them.

The axis of oscillation of the inner cage being adjacent its upper end, and the` shaft being mounted within the open top of the fixed cage, the rails of the inner cage exercise a squeezing and rolling movement on the clothes between them, and the rails of the fixed cage, which movement is particularly favourable to the expression of dirt from the clothes in the presence of the water in which the operation is performed.

In use, the tank 2 being filled to the required height with hot water and a suitable detergent, the clothes to be washed are charged into one or both of the ,spaces `between the outer railed cage 9, 10 and thenner cage 14, 15. The clothes, which ten "to float inthe water are, during oscillation of the inner cage, alternately forced down beneath by the rails 18 during movement of the inner cage in 'one direction, and during movement in the opposite direction, the inner side of the mass of the clothes is moved upward and squeezed yagainst the rails 10 of the stationary cage, the projecting edges of which tend to hold the clothes'against such upward movement, so that a rolling action occurs :during the squeezing action of' the innery cage against the outer. In the succeeding movementin the opposite. directiony the downward movement of the rail 18 tends lto loosen and open the mass as it is again pressed under the water.

`- ',The alternate loosening and .rolling and tank, a shaft supported in bearings' in the upper part of the tank midway between the walls of the cage, arelativelyA smaller inner cage secured to and downwardlyT projecting from, the shaft toV acent'the bottom of the tanlgthe walls of said inner cage being of spaced apart `rails and parallel to those ot the outer cage and similarly curved upward and outward from the bottom, said inner.

cage having also a rail projecting on each ide from the top over the space between the outer and inner cage, and means for oscillating the inner cage.

2. A washing machine, comprising in coml bination, a tank adaptedto hold water,'a centre board removably supported across .the

bottom of the tank, a cage, the walls of which ',arecomposed of spaced apart hori-i zontallyv disposed rails extending across be'- tween frames secured to the walls ofthe;

tanlnsaid wallsy being'curved upward and outward from the edges of the centrefboard to adjacent the top of the-tank, a rocking shaft extending across the upper part of the cage midway between its walls, said shaft mounted Ain bearings in the walls of the tank,

an innercage secured to the shaft and pro-k jecting downward to adjacent the vcentre boardthe bottomand sides of which inner Y cage are otspaced apart rails parallel to those ofthe outer. cage and the sides of which are curved upward and outward in similar curves, removable members out* wardly projecting from the upper side o'l the inner cage over vthe'spaces between it and the outer cage, rails secured to these outwardly projecting members, and means for oscillating the shaft.
